How many solar panels are needed for a house in Port-Gentil?

This is one of the most common questions Gabonese people ask before investing in solar energy: Exactly how many solar panels do I need to power my house? The honest answer is: it depends. But here's everything you need to know to get a clear picture.

What determines the number of panels needed?

It mainly depends on two things: your daily electricity consumption and the power output of each panel. The more electricity you use, the more panels you need. And the more powerful your panels are, the fewer you need.

Do all households have the same needs?

Absolutely not. A house with air conditioning has very different needs than one without. A 5-room house uses more energy than a 2-room apartment. That’s why WOW2000 always conducts a customized analysis before any installation.

A concrete example for a house in Port-Gentil

Let's take a typical home in Port-Gentil equipped with the following appliances: 4 LED light bulbs, 1 fan, 1 television, 1 refrigerator, and 1 phone charger. This type of household consumes an average of between 3 and 5 kWh per day.

How many panels does this house need?

With solar panels high-performance; 2 to 4 panels are generally sufficient to meet these daily needs under Gabon’s sunlight conditions.

What if I add air conditioning?

Air conditioning makes all the difference. It can consume as much energy as all your other appliances combined. In that case, you’ll need 6 to 10 panels, depending on the air conditioner’s power rating and the number of hours it’s used.

The Importance of Battery Storage

The number of panels alone isn't enough to determine your range. You also need to factor in a lithium battery with sufficient capacity to store the energy generated during the day and use it at night or in the event of a power outage.

What happens if we don't have enough panels? Your system generates less energy than you consume. You’ll therefore need to draw additional power from the SEEG grid—which is still a good way to lower your bill, but doesn’t provide you with complete energy independence.

What if we have too many signs? Excess energy charges your battery. This is ideal because it gives you a reserve for cloudy days or times of high energy consumption. To better understand the lifespan of your batteries, read our article on Lithium batteries in Gabon.
